Mesothelin Protein (MSLN) (AA 296-580) (Fc Tag,Biotin)

Catalog No. ABIN2444166

Product Details

Target: Mesothelin (MSLN)

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 296-580

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This Mesothelin protein is labelled with Fc Tag,Biotin.

Brand: MABSol®,UltraLys

Sequence: AA 296-580

Specificity: The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.

Characteristics: This protein carries a human IgG1 Fc fragment at the N-terminus. The protein has a calculated MW of 59.6 kDa. The protein migrates as 60-68 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.

Purity: >95 % as determined by SDS-PAGE.

Endotoxin Level: Less than 1.0 EU per μg by the LAL method.

Application Details

Comment:

A chemically labeled biotinylated protein with ultra sensitivity.
The product is produced using a chemical labeling approach. The primary amines in the side chains of lysine residues and the N-terminus of protein are conjugated with biotins.
Chemical labeling usually results in multiple biotin attachment on a single protein molecule, which could potentially lead to higher detection sensitivity.

Restrictions: For Research Use only

Handling

Format: Lyophilized

Buffer: PBS, pH 7.4

Handling Advice: Please avoid repeated freeze-thaw cycles.

Target Details

Target: Mesothelin (MSLN)

Alternative Name: Mesothelin (MSLN Products)

Background: Mesothelin (MSLN) is also known as CAK1 antigen, Pre-pro-megakaryocyte-potentiating factor, which belongs to the mesothelin family. Mesothelin / MSLN can be proteolytically cleaved into the following two chains by a furin-like convertase: Megakaryocyte-potentiating factor (MPF) and the cleaved form of mesothelin. Both MPF and the cleaved form of mesothelin are N-glycosylated. Mesothelin / MSLN can interacts with MUC16. The membrane-anchored forms of MSLN may play a role in cellular adhesion. MPF potentiates megakaryocyte colony formation in vitro.
